intersection of 2 strings

[Larry Bates]

At the risk of doing your homework,
one way would be:

list_1=string_1.split('_')
list_2=string_2.split('_')
#
# The next line uses some "magic" to eliminate duplicates"
#
list_3=[x for x in list_1 if x in list_2 if x not in
locals()['_[1]'].__self__]
string_3="_".join(list_3)
print string_3

If you have Python 2.3 you also could use sets() module
and it would be even easier.

HTH,
Larry Bates
